Control Options

The pump will provide a continuouslymodulated flow to meet changing loaddemands at a pre-adjustedcompensator pressure. At pressuresbelow the compensator setting, thepump will operate at maximumdisplacement. The compensator isavailable in two pressure ranges. TheC spring has an adjustment range of70 250 bar (1015 3625 psi). The CMspring has an adjustment range of40 130 bar (580 1885 psi).

C(M)*V Load Sensing andPressure Compensator Control

C or CM PressureCompensator Control

The pump will provide power matchingof pump output to system load demand,maximizing efficiency and improvingload metering characteristics of any

directional control valve installedbetween the pump and the load.

Load sensing ensures that the pumpalways provides only the amount of flowneeded by the load. At the same time,the pump operating pressure adjusts tothe actual load pressure plus a pressuredifferential required for the controlaction. When the system is notdemanding power, the load sensecontrol will operate in an energy-savingstand-by mode.

Typically, the differential pressure is thatbetween the pressure inlet and serviceport of a proportionally controlleddirectional valve, or a load sensingdirectional control valve. The standarddifferential pressure setting for loadsense is 20 bar (290 psi), but can beadjusted to between 17 and 30 bar (247and 435 psi) on the pump.

If the load pressure exceeds thesystem pressure setting, the pressurecompensator de-strokes the pump. Theload sensing line must be as short aspossible and can also be used forremote control or unloading of the pumppressure. For remote control purposes,it is recommended that you contact yourVickers representative for the correctconfiguration of the control.

Control Options

IC Compensator

Pressure Compensating Without Load Sensing

Pressure Compensating with Load Sensing

Pump with IC Compensator

This pump is intended for use whenmultiple, remote, or electrically

controlled compensating settings, withor without load sensing, are desired.

Pressure compensation is obtainedwhen an internal plug is removed, theload-sense signal port is kept plugged,and internal pilot pressure is applied tothe spring chamber of the control spool.For pressure compensation with loadsensing, the internal plug stays, theload-sense signal port is unplugged,and pilot pressure is externally applied.

An external relief valve (not supplied)controls spring chamber pressure.Theexternally adjustable spring determinesthe differential pressure setting of thecontrol. Outlet pressure is limited to thevalue of the spring chamber (pressureport) pressure, plus control differentialpressure.

Spring chamber (pilot) pressure isseparated from outlet pressure by aninternal orifice. Outlet pressure shifts thespool when pressure drop across theorifice reaches the differential pressuresetting, and the pump de-strokes.

The relief valve can be mounted to anNFPA-D03/ISO 4401-03 pad on thepump control, or remotely located viatapping and blanking plates installed onthe pad. See Ordering Procedure ,page 27, for more on valves and plates.

The standard factory-set differentialpressure setting of the pump control is20 bar (290 psi) and is not specified inthe pump model number. Any otherordered differential pressure, within thecontrol s adjustable pressure range of17 35 bar (247 508 psi), will bespecified in the model number followingthe IC control code; for example,-IC30- for a 30 bar setting.

Control Options

C**T Pressure and TorqueLimiter Control

The pump senses pressure and flowand starts destroking at apredetermined input torque level. Therate of flow reduction is normally tailoredto follow the maximum power capabilitycurve of the prime mover. Input torqueis limited while the pressurecompensator limits the system pressure.

When the input speed remains constant(i.e. industrial drives), the torque limiteracts as an input power limiter. Thisallows a smaller electric motor to beused if maximum pressure and

maximum flow are not required at thesame time. At low load levels, thecontrol permits high pump displacementand high load speeds. Under heavyloads, speed is reduced, preventingstalling of the prime mover. In the caseof variable speed drives (I.C. engines),this function provides, in addition topressure compensation or limiting, atorque limiting ability that can beadjusted to the torque/speedcharacteristics of the engine.

The start of torque limiting(pump-destroking) is pressuredependent. This pressure is selectable(see model code) and is factory presetto between 30% and 80% of themaximum pressure control setting. Theminimum torque pressure setting is 40bar (580 psi). Example: C10T4. There isno CM spring option available with thetorque limiting control.

Control Options

C**VT Pressure andTorque Limiting, PlusLoad Sensing, Control

The pump s control functions like aload sensing control, but with additionaltorque limiting tailored to the size of thedrive motor selected. The limitingfunction is the same as for a pressurecompensator with torque limiting (seeC**T description, previous page). Thecombination of the two controlsprovides the following benefits:

1. The energy savings of a variabledisplacement load sensing control.

2. The pump pressure follows the loadpressure.

3. The torque control allows smallerdrive motors to be used.

4. The pressure compensatorde-strokes the pump as maximumpressure is reached.

5. The pump pressure can also beremotely controlled using the loadsense line. The C**VT control allowscomplete control of flow andpressure, either mechanically orelectrically, if used with proportionalvalves.

Thru-drive Flange Kit and Shaft Coupling

*The basic PVH thru-drive pump has an SAE A pad on the rear. An SAE B or C pad rearmounting requires flange adapters. Required adapters can be provided if specified in thepump model code. The best combination of price, availability and flexibility is achieved byordering a PVH SAE A thru-drive model and the applicable PVH mounting flange adapterseparately. For example, a PVH74C-RCF-3S-10-C25-31 may also be ordered as aPVH74C-RAF-3S-10-C25-31 and a 876389 flange adapter.

** Thru-drive shaft couplings must be ordered separately to drive the second pump.

Typical Rear Pumps for Thru-drive Assemblies

NOTE: The above Vickers pumps are examples of rear pumps for the thru-drive pumps dimen-sioned on pages 21 and 22.The thru-drive torque limits identified in the chart on page 14 mustnot be exceeded when applying these multiple pump systems.

Fluid cleanliness

Proper fluid condition is essential forlong and satisfactory life of hydrauliccomponents and systems. Hydraulicfluid must have the correct balance ofcleanliness, materials and additives forprotection against wear of components,elevated viscosity and inclusion of air.

Essential information on the correctmethods for treating hydraulic fluid isincluded in Vickers publication 561;Vickers Guide to SystemicContamination Control, available fromyour local Vickers distributor or by

contacting Vickers, Incorporated.Recommendations on filtration and theselection of products to control fluidcondition are included in 561.

Recommended cleanliness levels,using petroleum oil under commonconditions, are based on the highestfluid pressure levels in the system and

are coded in the chart below. Fluidsother than petroleum, severe servicecycles or temperature extremes arecause for adjustment of thesecleanliness codes. See Vickerspublication 561 for exact details.

Vickers products, as any components,will operate with apparent satisfactionin fluids with higher cleanliness codesthan those described. Othermanufacturers will often recommendlevels above those specified.Experience has shown, however, that life

of any hydraulic components isshortened in fluids with highercleanliness codes than those listedbelow. These codes have been provento provide a long trouble-free service lifefor the products shown, regardless ofthe manufacturer.

Drive data

Mounting attitude should be horizontal.See preceding page for vertical mountoption. Consult your local Vickersrepresentative if a different arrangementis required.

Direction of shaft rotation, viewed at theprime mover end, must be as indicatedin the model designation on the pump.See 5 in Model Codes, page 4.

Cleanliness codes for petroleum oil usage

Drive arrangement should be bydirect drive through a flexiblecoupling. Check pump installationdrawing for concentricity and

squareness tolerances.

Torque capability of shafts in basic(non-thru-drive) pumps is well in excessof that needed for operation at ratedpressure and maximum displacement.Limitations for multiple pumps formed byPVH thru-drives as front-end sections arespecified in the chart on page 14.

Contact your Vickers representative foradditional information on the application

and ordering of relief valves.Installation and Start-up

The installation of PVH pumps must be inaccord with the data on pages 14 and 23.

Before the pump is started, fill the casethrough the uppermost drain port withhydraulic fluid of the type to be used.Thecase drain line must be connecteddirectly to the reservoir and terminatebelow the oil level. If the pump has thevertical-mount option, attach a secondarydrain line as noted on page 25.

Maximum continuous pressure at thecase drain port must not exceed 0,5 bar(7 psi). For multiple pump arrangementsthat include non-PVH sections, therequirements of the non-PVH units mustbe considered.
